In enzymology, an amygdalin beta-glucosidase (EC 3.2.1.117) is an enzyme that catalyzes the chemical reaction

(R)-amygdalin + H2O \rightleftharpoons (R)-prunasin + D-glucose

Thus, the two substrates of this enzyme are (R)-amygdalin and H2O, whereas its two products are (R)-prunasin and D-glucose.

This enzyme belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. The systematic name of this enzyme class is amygdalin beta-D-glucohydrolase. Other names in common use include amygdalase, amygdalinase, amygdalin hydrolase, and amygdalin glucosidase.
